new gpu, high refresh rate not working

Folivora · 2016-08-23 14:56:47

Hi all on archforum,

Using arch for a few years, but I still consider myself a newbie.
I just installed a new gpu and everything seemed to be working until I got into x. The screen got all wonky with weird lines and the screen says "cable incorrect, please use dual-link dvi cable" I turned the refreshrate back to 60hz and then the screen behaved normal again. the weird thing is that i'm pretty sure I'm using the right dvi cable since it worked fine with my older gpu and it worked fine in windows (never thought I would say that). Any ideas how to solve this? I allready reinstalled the drivers but didn't change much and I never configured a thing in x.
The only thing I can think off is that the rate of the dvi isn't high enough for 144hz, but i have no idea how to change that.

old gpu: amd 270
new gpu: amd fury
monitor: asus vg248qe
driver: xf86-video-amdgpu
resolution: 1920*1080
Connector: DVI-D(Dual Link)

NOTE: I don't have a displayport cable to test it, but it should be working with dvi anyway.

EDIT: added resolution and DVI

Follvora,

there are actually 5 types of dvi cables :
DVI-A(nalog) , DVI-DIigital) single link , DVI-D(igital) dual link, DVI-I(ntegrated) single link, DVI-I(ntegrated)dual link .
The connector pin-out tells you which you have, see https://en.wikipedia.org/wiki/Digital_V … #Connector

What type of cable do you have and which resolution are you trying to set?

Ok, cable and monitor should work then.

please post full dmesg , any *.conf files in /etc/X11/ and /etc/X11/xorg.conf.d/ folders , xorg log ,
"lspci -k" and xrandr output would also be useful.
(use a pastebin client for dmesg & xorg log ) .

Everything you asked is in the pastebin link.

you did post files in /etc/X11/xinit/xinitrc.d , but those are *.sh files, not the *.conf files i asked about.
the xorg log however indicates you don't have any of those.

there's no errors in the logs that i see, but a few things do stand out .

- you use an intel processor but haven't configured intel microcode updating

- your processor is an i7-4770k , according to this it has a built-in Intel® HD Graphics 4600 .
lspci -k doesn't show that, what have you done with it ?

- you are running linux-ck kernel, have you tried with stock kernel ?

I know I didn't had config files, but one sh file had DISPLAY in it so it might be something.

Microcode is fixed, thought I allready had it but I guess something went wrong while installing.

Rolled from linux-ck-haswell back to the default linux kernel with no succes

Intergrated gpu gets disabled with an descrete gpu in the bios by default (I think) and it might help with stability while overclocking so I keep it that way. It shouldn't be a problem though.

I change the refresh rate with lxrandr (it should fall back to previous refresh rate if you don't accept in 15 sec, xrandr doesn't) and everything went wonky again, and then it felt back to 60hz again and this happenend: https://www.dropbox.com/sh/mc50i0cvdftp … dqBia?dl=0
Not sure if dropbox links are allowed, but this is easiest for me.
In X it stays wonky, a different kind of wonky though, but far from working. The thing that worriest me the most is that the console was messed up aswell.

dropbox links may be frowned on (many people dislike relaxing security settings (javascript) just to see some pics) , but are ok for now.

Can you get dmesg / journal ouput from the period you made thoses photos ?

Do you get similar behaviour when using an older kernel ( 4.6.x , 4.5.x or even linux-lts) ?

Folivora, it looks like you hit report rather than reply:

I'll buy a displayport cable to see if that will help.

I blame mobile phones for that... Is it possible to revert that?
